GAS-HEATED STEAM-RADIATOR.

To all whom it may concern:

Be it known that I, WALTER M. Karenina, a citizen of the United. States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Gas-Heated Steam-Radiators, of which the following is a specification.

My invention relates to new and useful improvements 1n gas heated steam radiators,

and has for its object to provide an exceedingly simple and effective device of this character, whichmay be placed in a buildrelatively inexpensive in the cost. of manufacture, although strong and durable, which will need little or no attention during use, and which will produce a maximum amount of heat with the consumption of a minimum amount of fuel.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated bythe claims.

In order that those skilled in the art to which this invention appertains, may understand 110w to make and use the same, I

will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application, in which-.-

Figure .1 is a front elevation of a gas heated radiator constructed in accordance with my invention, portions thereof being shown in section, and parts being broken away to clearly illustrate the construction. Fig. 2 is a cross section of the heater.

In carrying out my invention as here embodied 2 represents a radiator of. any desirable size and construction adapted to stand upon the floor or hinge from the wall by means of brackets, and this radiator is provided with the. ordinary steam valve 3. At

Specification'of Letters Patent. Patent gd Aug, 21,1917, Application filed December 14, 1916. Serial No. 137,004..

one end of the radiator, and at the top thereof is connected a pipe 4 leading to the interior of the radiator, and to .the'outerend of this pipe is connected the T coupling 5. To the lower opening of this T coupling is connected one end of a pipe 6, the opposite end being connected with one of the open ings of the reduced T coupling 7. Intermediate the ends of this pipe 6 is arranged a try-cock 8 which acts as a water gage, and which may be opened when the radiator is being filled with water to prevent the contents of the radiator reaching a greater height than the position of this try-cock 8.

To one of the other outlets of the coupling 7 is connected a horizontal pipe 9 running the entire length of the radiator somesuit- I able distance below the same, and to this pipe is connected an'elbow coupling lO havmg one end of a pipe 11 connectedthereto,

and to the oppositeend of this pipe is con iected another elbow 12 to which is connected a pipe 13 running to the opposite end of the radiator at the bottom thereof, and

communicating with the interior of said 1 radiator.

In the upper outlet opening of the T coupling 5 is threaded a filling cup or funnel lel having external and internal threads in the stem portion thereof. This filling cup permits the water to be readily placed in the radiator without the likelihood of spilling the same, and when the radiator is filled to the proper capacity, a suitable closure or closing plug 15 is threaded into the threaded portion of the filling cup, and this closure is provided with a suitable stem or handle 16, whereby the same may be readily and quickly removed or replaced, and this stem or handle projects above the upper edge of the filling cup when the closure is in its closed position.

In the reduced end or outlet of the T coupling 7 is mounted a pet-cock 17, whereby the contents of the radiator may be drawn therefrom. The fire box 18 'ismounted upon and supported by the pipe 9, said pipe projecting through both .ends of said fire box and the walls of this fire box are imperforate. This fire box has one open side which is normally covered by a lid 19 hinged to one of the walls of the fire box by means of hinges 20, and this lid is provided with perforations 21 for the admission of air to the fire box, thus providing for the proper combustion of the gas within the fire box. may be held in a, closed position by a suit able catch 22.

That portion of the pipe 9 situatedwithin the fire box is preferably covered with a jacketeror sleeve 23 of copper or other suit-e able metal having high fire resisting properties, and this sleeve or jacket also acts as a heat retainer and transmitter, so that the water" in the pipe 9 will" be readilyraised in temperature until steam isfinally produced therefro1n,- which will circulate throng-l the pipes 9, 6 and-4, thenithrough the radiator; whereby it will gradually cool and condense and return to the lower portion of the radiator in the form-of water,

from which pointitwill circulate through the pipes 13 and 11 into the pipe 9 to-be again heated and turned into steam.

In-the; fire box 18 belowthe pipe 9'is arranged a gas burner 24 m the form ofa Bunsen burner, so that a veryhot, blue fiameywill be produced, and this burner is connected by a pipe 25 or; itsequivalent, such as-a hose, with the gas supply pipe 26 in the form of anoutletpipe or" gas fixture.

In actual practice it is only necessary to; replen-isl1,the radiator with water; in small amountsevery-one or two weeks, and. it hasbeen found; that the consumption ofgas is very-small; so thatit will'be understood that my" radiator may be. installed in; houses,

which at the present time do not use steam becauseof theexpense of installing such If found desirable this lid 1.
